How to Fix Phone Overheating in 2025 (Complete Guide)
If your phone feels hotter than usual, loads slowly, or drains battery quickly, you’re not alone. Millions of users worldwide deal with phone overheating, especially during gaming, streaming, charging, or running modern apps. In 2025, phones are more powerful, but they also generate more heat due to high-performance processors and AI-driven apps.
Many users search for ways to fix phone overheating in 2025, especially with newer phones running hotter under heavy load.
The good news? Most overheating issues are easy to fix. In this guide, you’ll learn why your phone overheats and the best ways to cool it down and prevent long-term damage.
1. What Causes Phone Overheating in 2025?
Understanding the cause is the first step to fixing the issue. The most common reasons include:
• Heavy apps running in the background
AI apps, social media, and games push your CPU and GPU.
Heavy AI apps, high screen brightness, and poor charging habits are some of the most common reasons people need to fix phone overheating today.
• High screen brightness
Bright screens generate heat and drain battery faster.
• Poor charging habits
Using cheap chargers or fast charging constantly increases heat.
• Weak signal or unstable network
Your phone works harder to maintain connection.
• Direct sunlight exposure
Heat builds quickly when using your phone outdoors.
• Dust blocking ventilation
Even small dust particles trap heat inside the device.
2. Quick Fixes to Cool Down an Overheating Phone
Before trying anything advanced, use these instant fixes.
✔ Close background apps
Swipe away unused apps and stop background processes.
If you want to fix phone overheating fast, the easiest solution is to close background apps and avoid charging during gaming.
✔ Remove the phone case
Cases trap heat. Remove it until your phone cools down.
✔ Lower brightness
Set it to Auto or below 50%.
✔ Disable 5G temporarily
5G heats up devices when signals are weak.
✔ Stop fast charging
Use normal charging unless necessary.
✔ Restart your phone
This clears memory and resets overheating apps.
If you want to fix phone overheating quickly, start by closing heavy apps and reducing background processes that spike CPU usage.
3. Change These Settings to Prevent Overheating
These setting tweaks reduce heat long-term.
• Turn off Bluetooth, NFC, and GPS when not needed
Background scanning causes heat spikes.
• Reduce refresh rate (90Hz → 60Hz)
High refresh rates make your phone hotter.
• Disable background data for heavy apps
Apps like TikTok, Instagram, and Snapchat run constantly.
• Limit notifications
Background sync spikes CPU usage.
• Enable battery saver mode
This reduces heat by lowering processor load.
4. Advanced Fixes (If the Overheating Persists)
If your phone is still overheating, try these deeper solutions.
• Clear App Cache
Go to Settings → Apps → Storage → Clear Cache.
• Update your operating system
Bug fixes often reduce heat and battery drain.
• Uninstall old or buggy apps
Outdated apps cause overheating issues.
• Reset network settings
Fixes signal-based overheating.
• Factory reset (last resort)
This removes deep system issues but should only be done if everything else fails.
5. Best Apps to Monitor Phone Temperature (2025)
These apps help you track heat in real-time:
- CPU Monitor
- Cooling Master
- Device Info HW
- AccuBattery (Highly recommended)
They show CPU load, battery temperature, and background processes.
6. How to Keep Your Phone Cool Long-Term
Prevention is better than fixing.
• Avoid charging while playing games
This overheats both battery and motherboard.
• Use certified chargers only
Cheap chargers increase heat + risk.
• Keep your phone away from sunlight
Especially while driving or outdoors.
• Give your phone 10–15 minutes of rest every 3–4 hours
Helps the processor cool down.
• Don’t overload with apps
Less clutter → less heat.
7. When Is Overheating Dangerous?
Seek professional help if:
- your phone shuts down by itself
- battery drains extremely fast
- the back of the phone becomes too hot to touch
- camera apps crash frequently
- device becomes slow or freezes often
These may indicate:
- damaged battery
- swollen battery
- failing motherboard
- thermal throttling
If this happens, visit an official repair center.
Final Thoughts: Fixing Phone Overheating in 2025
By following these steps consistently, you can fix phone overheating problems long-term and improve overall device performance.
Phone overheating is a common issue in 2025, but most cases are caused by heavy apps, charging habits, and background processes. By using the steps in this guide, you can cool down your device, improve battery life, and prevent long-term damage.
If the issue continues, consider reaching out to a professional technician or checking if your device is eligible for warranty repair.
Is Overheating Becoming More Common in 2025?
Overheating issues are more common in 2025 because modern apps rely heavily on real-time processing, AI-enhanced filters, and background analytics. Many phones are now used for longer video calls, HD streaming, and high refresh-rate gaming. As these tasks push processors harder, heat naturally increases. By managing your settings, avoiding heavy multitasking, and keeping your apps updated, you can dramatically reduce heat and improve your phone’s overall lifespan.
